An unexpected candidate might challenge Hillary for the Democratic nomination: former Vice President Al Gore.

That’s right: the global warming huckster who came just 537 Florida votes away from the White House fifteen years ago might be throwing his hat in the ring, and challenging the wife of his former boss for a shot at the big time.

Gore’s supporters have already started the chatter, apparently.

Buzzfeed reported that an anonymous top-ranking Democrat confirmed Gore might be interested. Gore and his supporters are apparently “figuring out if there’s a path financially and politically… It feels more real than it has in past months.”

The claim that Gore might be readying a presidential run comes as Hillary Clinton is under increasing scrutiny over her email scandal–and terrifying Democrats as her star continues to fall.

Worse, as Americans continue to lose trust in Clinton, she’s seen even massive drops among Democrats: Sen. Bernie Sanders, the self-styled socialist Senator from Vermont, now leads her in polls for the must-win New Hampshire primary.

While Hillary remains the Democratic frontrunner–and the likely Democratic nominee–it’s clear that she might be drawing stronger challengers, despite months of clearing the path for her nomination. Vice President Joe Biden is also rumored to join the 2016 fray.

Despite Hillary’s hope to skip through the primaries as a “coronation,” it’s clear that she’ll have a much tougher road to the nomination–and much more of an uphill road back to the Oval Office–than anyone anticipated.
